To all whom it may concern:

Be it known that I, FRANCIS THOMAS Mo- DONOUGH, a citizen of the UnitedStates, residing at Eau Claire, in the county of Eau Claire and State ofWisconsin, have invented a new and useful Adjustable Band Saw Guide, ofwhich the following is a specifica tion.

The present ap lication is a division of the a plication filed fiy meMar. 20, 1907, Serial 1 0. 363,526, for an im rovement in horizontalband resawing mac incs, and relates to a saw guide.

The object of the present invention is to improve the construction ofsaw guides, and to provide an adjustable guide for band saws, capable ofbeing readily operated from the front of the machine to move the saidguide either inwardly or outwardly.

lVith these and other objects in View, the invention consists in theconstruction and novel combination of parts hereinafter fully described,illustrated in the accompanying drawings, and pointed out in the claimshereto appended; it being understood that various changes in the form,proportion, size and minor details of construction, within the scope ofthe claims, may be resorted to without departing from the spirit or'sacrificing any of the advantages of the invention.

In the drawings :--Figure 1 is a rear elevation of a portion of ahorizontal band resawing machine, provided with an adjustable saw guide,constructed in accordance with this invention. Fig. 2 is a sideelevation of the same. Fig. 3 is a plan view. Fig. 4 is an enlargeddetail sectional view, takenlongitudinally of the saw guide on the line4-4 of Fig. 1. Fig. 5 is a similar view, taken substantially on the line55 of Fig. 4. Fig. 6is a similar view, taken substantially on the line66 of Fig. 4.

Like numerals of reference designate corresponding parts in all thefigures of the drawings.

The band wheel guard 286 constitutes a support for an adjustable bandsaw guide 287, which is operable from the front of the machine toarrange it in the desired position. The adjustable band saw guide ismounted on the inner end of the slide 288, disposed horizontally andarranged edgewise vertically and having beveled upper and lower edges289 to fit in a dove-tail way 290 of the band saw guard 286. The bandsaw guard 286 is provided at the top with an extension aving upper andlower longitudinal flanges, which have oppositely inclined inner facesto provide the dove-tail way 290. The slide is also provided adjacent toits end portions with inner and outer projecting lugs 291 on which aremounted eye bolts 292 for the attachment of a Wire rope 293, chain orother suitable flexible connection, which is wound around a drum orspool 294. The drum or spool 294 is mounted on the rear end of a shaft295, which extends to the front portion of the machine and which isprovided at its front end with a hand wheel 296 for enabling it to beconveniently turned to move the adjustable slide inwardly and outwardly.The flexible connection 293 extends in opposite directions from thespool or drum, and when the shaft is rotated, one of the end portions ofthe rope will be wound up on the said spool or drum and the other willbe unwound therefrom. The portion being wound on the spool or drum movesits attached end toward the same and actuates the slide 288. Theadjustable saw guide is adapted to be moved across the saw table 85, andis employed except when cutting very thin stock, when it is moved beyondthe edge of the table. The shaft 295 is mounted at its rear end in asuitable bearing 297 at the top of the dove-tail way, and it issupported near its upper end by an arm 298, extending laterally from theouter face of the column 7 and terminating in a bearing.

The slide 288 is provided at its inner end with a foot 299, having adove-tail way 300 at its lower face to receive an adjustable lowermember 301 of the adjustable guide 287. The lower member, which issecured in its adjustment by set screws 301 is provided with a dove-tailenlargement 302, slidable in the dove-tail way 000 and engaged by theset screws 301, and the said lower member has a knob 303 to enable it tobe readily moved backwardly or forwardly to arrange it properly withrelation to the baud saw, and also to enable the said lower member 301to be readily detached, when it is desired to remove the band saw fromor place the same on the band saw wheels.

The band saw guide 287 is also provided with an adjustable upper member304. The member 304, which is approximately L- shaped, has a verticallydisposed portion 305 fitted against the upper end of the horizontalslide 298, and extending upwardly therefrom and adjustably secured tothe same by means of a screw 306, mounted in a vertical slot 307 of theslide 288 and engaging a threaded perforation of the vertical portion ofthe upper member 30-1. The horizontally disposed. portion of the uppermember 304 extends forwardly from the slide, while the foot .299projects rearwardly therefrom. The lower member 301 is provided withadjustable saw-supporting screws 308, and the upper member carriesadjustable saw-engaging plates 309 and. 310 for holding the band sawagainst downward or upward movement.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is 1 1. In a sawing machine, thecombination with a horizontal band saw, of a band saw guide including asupport having a vertical portion located at one side of the band sawand arranged above the plane of the same, an upper guide member alsolocated above the band. saw and provided with a vertical portion fittedagainst and adj ustably secured to the vertical ortion of the supportand movable upwardly and downwardly toward and from the band saw, and alower guide member connected with the support and extending beneath thesaw.

2.
